Specifically, Genius maximizes a single ally's Magic Power, regardless of level allocation. Because of this, it is wasteful to set Genius and other Buff/Debuff Elements any higher than the level 1 allocation spot on an Element Grid. Although this will depict the Element as being -3, no quality difference is noticeable in-game; the character with Genius cast on them will still receive the same boost to Magic Power for several turns.

Similar to the animation for Imbecile, under the target's feet, a glyph of violet symbols appears. Shortly after, several strings of light shoot up and enclose the target in a vortex, with lopsided rings of darker violet running up the vortex as well.

Genius is an accolade to the intelligence of a person. A certified genius not only thinks more quickly than the average human, but also exhibits expertise in a specific subject or vast numbers of subjects. Since spell-casting and magical ability is often attributed to one's intelligence, increasing intelligence or one's faith in their intelligence would thus increase magical ability.
